The perfect solution for:
• Applications with older motors
• Aggressive environments
• Applications with frequent braking
• 690 V applications with general purpose motors
Prevent disturbing pulses
Sine-wave filters prevent disturbing pulses to be transmitted to downstream motors. Capacitances in screened motor supply cables can otherwise cause high oscillating circuit currents through motor bearings, vaporising lubricant and causing damage to the bearings. The eddy current losses in the motor can also be minimised in this manner, resulting in a cooler motor and thus extended motor life-time.
Caratteristiche e vantaggi
Protects the drive
In addition to protecting the motor, the sine-wave filter also provides protection for the inverter, because the lower pulse load is reflected in lower semiconductor losses.
Advantages:
• Protects the motor against dU/dt stress which prolongs the lifetime
• Lowers the frequency depending losses in the motor, eddy current losses and stray flux losses
• Diminishes acoustic switching noise on the motor
• Reduces semi conduct losses in the drive with long motor cables
• Decreases electromagnetic radiated emissions on unscreened motor cables • Reduces voltage peaks
• Reduces electrical discharges in the motor construction thus prolonged bearing life time
• Compatible with all control principle including flux and WC+
• Parallel filter installation is possible with applications in the high power range
